In this study, we report three insect pest species of non-astringent persimmon, Pleuroptya chlorophanta, Acria ceramitis, and Choristoneura longicellana, for the first time from Korea. Larvae of these species were collected from an organic farming persimmon orchard in Changwon city, Gyeongnam province, and reared in the laboratory to be identified in 2012. Some information, such as collection records, hosts, simple morphological characteristics, and ecology were introduced for each species.
